                Configures the database environment's base segment ID.
                This base segment ID will be used when Berkeley DB shared
                memory regions are first created.  It will be incremented a
                small integer value each time a new shared memory region is
                created; that is, if the base ID is 35, the first shared
                memory region created will have a segment ID of 35, and the
                next one will have a segment ID between 36 and 40 or so.

                line with the string <code class="literal">set_shm_key</code> one or
